A Performance Prediction Method for Pumps as Turbines (PAT) Using a CFD Modeling Approach
Small and micro hydropower represents an attractive solution for electricity generation, with low cost and low environmental impact. The pump-as-turbine (PAT) approach has promise in this application owing to its low purchase and maintenance costs. In this paper, a new method to predict the inverse characteristic of industrial centrifugal pumps is presented. This method is based on results of s...

متن کاملQuery Performance Prediction for Analytical
of “ Query Performance Prediction for Analytical Workloads ” by Jennie Duggan, Ph.D., Brown University, May 2013 Modeling the complex interactions that arise when query workloads share computing resources and data is challenging albeit critical for a number of tasks such as Quality of Service (QoS) management in the emerging cloud-based database platforms, effective resource allocation for time...
متن کاملA method of performance estimation for axial-flow turbines based on losses prediction
The main objective in this paper is creating a method for one-dimensional modeling of multi stage axial flow turbine. The calculation used in this technique is based on common thermodynamics and aerodynamics principles in a mean stream line analyses. In this approach, loss models have to be used to determine the entropy increase across each section in the turbine stage. Finally, the analysis an...
